Like we know, Powerrade, Gatorade and other sports drinks contain
carbohydrates and
electrolytes. - Which benefits are there in drinking it?
Electrolytes are extremely important when doing cardio on hot days over extended periods of time (1h+). When you drink much water, you will after some time dilute the salts in your body which can lead to Hyponatremia. Therefore it is important to constantly fill up with salts. Mens Fitness writes: "Excessive water intake will dilute blood plasma and may result in Hyponatremia (water intoxication) where blood sugar levels drop dangerously low. Taking electrolyte drinks and salty foods [...] will help to offset the likelihood of this accruing"1
So the conclusion is that you should either get a sports drink or just pore in some lemon and salt in your water. 0.5l pr. hour (of electrolyte drink) will do.
carbohydrates is your fuel and it is therefor important to constantly fuel up. By eating around 50g of carbohydrates each hour you will be sure not to run out of fuel or "hit the wall". As a rule of thumb you usually say 1 piece of food each hour. 1gel, 1bar, 1banana etc. Although if you workout is under 1 hour you will be fine without any food.
Remember to stay hydrated and fueled up! :)
